Tried to retrieve this and was sent a code but when I used it, it says 'this product is not registered'?!
A license purchased for a certain version is also valid for the subsequent version, but not for the version following that.
So, a license purchased for version 4 is also valid for version 5, but not for version 6.
Of course, you can continue to use the version for which you have a valid license for as long as you like.
In case you want to upgrade, you can get an upgrade link via our website (under the Help tab).
We will send you an email with a link to purchase the upgrade. As an existing customer, you'll get a 50% discount on the regular price.
When you buy the upgrade, you'll receive a new license that needs to be entered in the AnyRail program to register it.
